Just hours ago, SpaceX successfully launched its second batch of 60 Starlink satellites, featuring a variety of upgrades as part of the move from v0.9 to v1.0 spacecraft. During SpaceX’s launch webcast, the hosts revealed a number of intriguing new details about those upgrades, shedding a bit more light on what exactly has changed.

SpaceX launched its first dedicated Starlink mission in May 2019, placing 60 “v0.9” satellites in low Earth orbit (LEO) in what was essentially a beta test at an unprecedented scale. At the time, SpaceX and CEO Elon Musk disseminated a substantial amount of information, essentially taking the veil off of (part of) the company’s Starlink satellite program. In terms of the basics, Starlink v0.9 satellites were said to weigh approximately ~225 kg (500 lb) apiece, although the final mass – said to be the heaviest payload SpaceX had ever launched – suggested that that figure excluded the mass of krypton propellant.

All told, Musk said that the payload weighed ~18.5 tons but never clarified whether that was in imperial or metric units, leaving a potential range of 16,700-18,500 kilograms (36,800-40,800 pounds). In general, Musk was quite confident that SpaceX’s custom-built phased array antennas were effectively the best in the world even in their v0.9 beta-test iteration. Additionally, he noted that inter-satellite optical (i.e. laser) links would have to wait a generation or two before becoming part of the operational constellation.

Ch-ch-ch-changes

With SpaceX’s Starlink-1 launch, the second 60-satellite mission, the company debuted Starlink ‘v1.0’ satellites with a range of changes and upgrades that fall under two main categories: structures and communications.

Prior to the November 11th webcast, SpaceX’s official pre-launch press kit was far less revealing than Starlink v0.9’s but did note that v1.0 satellites have been upgraded to be “100% demisable”. This means that when each spacecraft reenters Earth’s atmosphere, everything down to the last shred of mylar is now expected to burn up before reaching the ground, reducing the (already miniscule) risk of debris harming people or property. Similarly, SpaceX implied several months before launch that v1.0 spacecraft would include tweaks to limit their reflectiveness after the astronomy community stoked fears about potential impacts.

Aside from a general improvement to the overall visual fit-and-finish of the v1.0 spacecraft, SpaceX’s official comments on the matter indicated that the most substantial changes between v0.9 and v1.0 were more related to each spacecraft’s advanced electronics and payloads. In the case of Starlink, each satellite’s primary payload is a high-performance suite of electronically-steered phased array antennas. Initially developed to improve the flexibility of tracking and scanning radars used by military fighter aircraft, phased array antennas (and radar) allow multiple beams to be aimed without physically moving the antenna.

SpaceX says that Starlink v1.0 satellites added a number of Ka-band antennas alongside upgraded Ku-band hardware similar to what was installed on Starlink v0.9. Ka and Ku refer to similar but different communications frequencies, with Ku-band generally offering greater reliability and cloud/rain tolerance, while Ka-band is a bit more sensitive to environmental factors but offers a substantially higher theoretical bandwidth.

According to SpaceX engineers speaking during the Starlink-1 launch webcast, Starlink v1.0 satellites offer an unexpected 400% increase in overall bandwidth, meaning they can theoretically transmit four times as much data per any given second. Additionally, Starlink v1.0 satellites were said to feature antennas with twice as many steerable beams, meaning that they can effectively serve two times as many regions simultaneously. It’s unclear if the addition of Ka-band antennas is the sole source of these substantial improvements.

Furthermore, during the Starlink v0.9 launch, SpaceX CEO Elon Musk indicated that the 60 satellites represented a bandwidth of more than 1 terabit per second (Tbps), translating to ~17 Gbps per satellite. More likely than not, Musk was speaking aspirational and the v0.9 satellites actually represented more like ~200-300 Gbps worth of throughput, with the additional of Ka-band antennas and perhaps general technology upgrades bringing v1.0 satellites to a nominal ~17 Gbps apiece.

For now, 60 Starlink v1.0 satellites are now in orbit and are rapidly spreading out after their bizarre but effective blob-style deployment. With any luck, all 60 will successfully deploy their solar arrays and begin propelling themselves towards their final operating orbits with krypton-fueled ion thrusters.

The Boring Company’s newest Vegas Station has a permit quietly waiting behind it

Sahara Las Vegas opened a new Vegas Loop station, joining an exclusive two resort transit club.

Sahara Las Vegas opened a new Vegas Loop station Thursday, giving The Boring Company’s underground transit system its northernmost stop yet on the Strip. The station sits at Sahara’s Paradise Road entrance, on the southeast corner of Las Vegas Boulevard and Sahara Avenue, and connects riders to the Las Vegas Convention Center, other Strip resorts on the network and, eventually, Harry Reid International Airport.

The addition makes Sahara the second resort, after Fontainebleau opened its own station in January, to get a stop built at street level rather than tucked into the property itself. Sahara now joins Westgate as the only two Strip resorts offering both a Vegas Loop station and a stop on the Las Vegas Monorail, giving guests two separate ways to get around without leaving the property.

The Boring Company just doubled its tunneling power in Nashville

The bigger news buried in Thursday’s announcement is what comes next. Boring Company has already secured its first permit to tunnel north of Sahara Avenue, extending the network beyond where it currently ends, even though permits to push the Loop toward downtown Las Vegas still haven’t been granted. Crews are also working on a two mile dual tunnel line running from Westgate to a planned station at 4744 Paradise Road, just north of Tropicana Avenue, that Las Vegas Convention and Visitors Authority CEO Steve Hill has said the company hopes to open in time for November’s Las Vegas Grand Prix.

Ridership has grown alongside the buildout. The Loop moved roughly 82,000 passengers during CONEXPO in early March, a total the company highlighted on its own X account at the time, and the system has now carried more than 4 million passengers through 11 open stations since it began running in 2021. The airport connector tunnels, meant to give the Loop a direct link to Harry Reid, have slipped past their original first quarter target and remain under construction, with Boring Company director Mike Baier saying that a full opening is still a few months out.

For Sahara, the calculation is straightforward. Convention traffic drives a large share of Loop ridership, and a station at the property’s front door gives conventiongoers one more reason to book rooms on the Strip’s north end instead of closer to the convention center itself.

Tesla’s mysterious Robovan makes a sneak peek with Optimus in Terafab video

SpaceX Terafab rendering

Elon Musk posted a new video of Terafab on X Thursday morning, and the most eye-catching details in it were not the building itself, but two products still awaiting production: Optimus and the Robovan.

The concept render, credited to SpaceX, shows Optimus robots working the grounds of the roughly 2.5-mile-long facility planned for the Gibbons Creek site in Grimes County, while a Robovan glides along an elevated roadway cutting through the building itself, sharing the frame with a Tesla Semi and a Cybercab.

Robovan is the boxy, driverless people and cargo mover Musk unveiled alongside Cybercab at Tesla’s “We, Robot” event in October 2024. He pitched it as a way to move up to 20 passengers at once, or handle freight instead, at a target cost he claimed could fall under a dollar a mile, with no steering wheel or pedals, the same layout as Cybercab. Nearly two years later, Robovan still has no confirmed production timeline and has not shown up in any factory footage, which makes Thursday’s render one of the only recent looks at the vehicle in any form.

Optimus has moved further along. Tesla began converting Fremont’s old Model S and Model X assembly line into a Gen 3 Optimus production line earlier this year, and Musk visited the site on July 1 to mark the changeover. A second, larger Optimus plant is under construction at Giga Texas, targeting volume production in summer 2027 and eventual capacity of 10 million units a year. Tesla AI lead Ashok Elluswamy said this month the robot has “big shoes to fill” in replacing the S and X line, while Musk has repeatedly called Optimus the company’s biggest product of any kind, with a long-term price he has pegged between $20,000 and $30,000.


“Terafab Texas will be the largest and most valuable building on Earth by far,” Musk wrote alongside the clip. “And it will be stunningly beautiful.”

One quote post summed up the reaction: “Futuristic scene with RoboVan + Cybercab + Tesla Semi + Optimus.”

Beyond the vehicles, the architecture wrapped around them stands out too. The building’s facade is canted at sharp angles, with illuminated horizontal bands running through what appears to be a multi level interior visible from outside. Below the elevated roadway, pedestrians walk along a plaza next to a reflecting pool, and the skyline behind the campus is dotted with angular spires that read more like sculpture than infrastructure, a departure from the strictly utilitarian look of Gigafactory Texas or Starbase.

The timing tracks with what Terafab representative Riley Trennell told Grimes County residents on Wednesday, when he said renderings of the facility would be released “within days.” Musk’s post followed less than 24 hours later, and Texas Governor Greg Abbott’s office sent out its own release Thursday confirming the project. As Teslarati reported this morning, Terafab’s tax abatement agreements with Grimes County are now signed and active, and SpaceX has sent the county its first $10 million payment under that deal. The dollar figure tied to this phase of construction, per Reuters, is $16.8 billion, one of the first hard capital expenditure numbers attached to Terafab since Musk unveiled the joint Tesla-SpaceX-xAI venture in March.Reaction on X ranged from enthusiastic to skeptical. “God Bless Texas! Everything is bigger and better in Texas!” one reply read. Another was more measured: “Terafab in a decade…..”

Whether the finished building matches the render is a separate question from whether Musk wanted people talking about the render itself. Less than a day after posting, the video had already crossed 5.5 million views.

Tesla Cybertruck production snaps back after ugly supplier fight

Cybertruck production at Giga Texas is showing its first visible recovery since Tesla sued a supplier last month over withheld manufacturing tooling.

Aerial observer Joe Tegtmeyer flew over the Austin factory Wednesday morning and counted roughly 100 or more Cybertrucks filling the outbound lot, a sharp jump from the thin numbers seen in recent weeks. The flyover came a day after a judge granted Tesla a temporary restraining order against Angstrom Automotive Group, the parts supplier at the center of the dispute.

Tesla filed an emergency lawsuit in late July after Angstrom told the automaker it planned to close the Troy, Texas facility where Tesla’s die-cast tools, trim dies and other Cybertruck stamping equipment were housed. According to Tesla’s complaint, a shipment of 700 finished parts never left the building, and when Tesla sent representatives to retrieve its equipment, accompanied by law enforcement, they were turned away. Angstrom allegedly then asked for an extra $250,000 a week to keep operating, which Tesla’s filing described as holding its own property for ransom.

Tesla quietly made the Cybertruck even stronger

The restraining order gives Tesla immediate right of entry to Angstrom’s facility to recover the tooling. It is temporary, with a fuller hearing still to come, but the speed of Wednesday’s rebound suggests the Angstrom shortage was indeed the main bottleneck limiting Cybertruck output. Outbound lot counts are an imperfect measure of actual production, since finished trucks can sit for days before shipping, but a lot that full after a lean stretch is a meaningful signal.

Cybertruck output at Giga Texas has fluctuated all year as Tesla worked through supply issues and introduced new trims, including a cheaper Dual Motor AWD version that drew strong early demand.
